JOHX E. PRUNTY, OF'BALTIMORE, MARYLAND.

NOZZLE.

EBI ECIFIGATIQN forming part of Letters Patent No. 318,800, dated May 26, 1885.

Application filed January 26, 1885.

To all whom it may concern.-

Be it known that I, JOHN E. PRUNTY, of the city of Baltimore and State of Maryland, have invented certain Improvements in Hose- Pipe Nozzles, of which the following is a specification.

This invention. consists in certain improvements on Letters Patent'No. 245,559, granted to me on the 9th day of August, 1881, for a hose-pipe nozzle. The said invention consists in a peculiarconstruction of the nozzle to produce lateral and radial streams of water therefrom, as will hereinafter fully appear.

In the drawings forming apart hereof, Fig ure I is a longitudinal view of the improved nozzle, the same being shown partly in section. Fig. II is a crosssection on the dotted line a;

A is a part of ahose-pipe nozzle.

B is an annular chamber formed around a part of the nozzle and in communication with the interior thereof by means of holes a. The chamber B has a narrow annular outlet, I), which extends therefrom rearward at an angle of about sixty degrees. The metal of the pipe in front of the lateral outlet 6 projects asa lip, G, radially beyond the said outlet, and the lip has a face, 0, leading forward at an angle of about forty-five degrees.

D is a threaded sleeve provided with handles E, by means of which it is turned, having an inclined face corresponding in angle with the face 0 of the lip 0 just described. By means of the sleeve the lateral escape of water from the interior of the pipe can be cut off or a funnel-shaped discharge effected, the thickness of the sheet of water being regulated by the width of the discharge-aperture disclosed by the backward movement of the said sleeve. When the forward funnel-shaped dis- (N0 model.)

charge is being used, the outlet b is merely a feeder or supply-aperture, and its angular position is of no value; but when the sleeve is drawn back beyond a radial line continued from the angular inner face of the outlet 6 a rear funnelshaped sheet of water is produced independently of the lip O. From this disscription it will be understood that the pipeman can at pleasure direct the lateral dis charge rearward to protect himself, or forward to act as an extinguishing agent. In order that a tight joint may be formed between the sleeve and the lip O the former is provided with a ring of packing material, cl, preferably gum, as shown in Fig. I. To .prevent the water being forced past the holes a, owing to its velocity of discharge through the pipe A when the shut-off cock, which is not shown, is open, the portion ofthepipe immediately in front of the holes a. is contracted in diameter, as shown, which has the effect of slightly packing the water and causing it to seek a means of escape through the said holes to the annular chamber B, and thence to the outlet b.

I claim as my invention A hose-pipe nozzle having an annular chamher around the same in communication with the interior of the nozzle by means of suitable holes,and an angular outlet leading rearward, combined with a lip having an inclined face leading forward, and a longitudinal moving sleeve adapted to be forced toward or from the said lip, substantially as and for the purpose specified.
